The crocheting process itself didn't take long. However, considerable effort was required to fix the eyes with a diameter of 30 mm,
and I had to restart crocheting the flower petals several times.
Nevertheless, the entire creation process took several hours.
The most time-consuming parts were collecting and processing data, as well as searching for a suitable pattern and encoding the information.
P.S. A significant advantage of creating such toys for myself, rather than for sale, is their environmental friendliness: I used remnants of yarn for knitting, and part of the toy was stuffed with thread clippings from other projects.
